The problems existing in the prior art are as follows: after the construction of the window is finished, a water spraying test is needed to test the waterproof performance of the window so as to repair the defects in time. However, during the water spraying test, a large amount of water flows onto the outer vertical surface of the building and then flows downwards along the outer vertical surface of the building. The problem is not great if the concrete is bare at this time. However, if the exterior wall insulation layer and the exterior wall decoration which are already carried out or finished are arranged below the heat insulation layer, the remained sewage can affect the heat insulation performance of the insulation layer and can smear the exterior wall decoration. The heat preservation construction of the outer vertical surface and the decoration construction of the outer vertical surface are necessarily carried out after the water spraying test is finished after the window is installed.
The outer wall which is just poured and demoulded is not suitable for immediately carrying out heat insulation construction on the outer wall, so that the current situation that the installation construction and the water spraying test of a window are carried out after the existing main body construction is capped, and then the heat insulation construction and the decoration construction of the outer facade are carried out is caused.
In addition, in the construction of a window in the prior art, the construction of the window sub-frame is generally earlier, and the window sub-frame is already installed at the lower part when the construction of the building main body is performed at the upper part. And then, the main window frame and the glass are installed after the building is capped, so that the construction interval between the auxiliary window frame and the main window frame is longer, and the installed auxiliary window frame is easy to fall into gravel and pollutants such as rainwater in the groove. When the main frame of the window is constructed, the main frame needs to be cleaned up firstly. And the rainwater of window subframe memory is difficult to complete clean up, when setting up waterproof filler material, the waterproof effect of filler material is influenced to the rainwater that exists. Affecting the water resistance of the whole window.
Compared with the prior art, the cast-in-place building outer wall construction method based on the climbing frame has the following beneficial effects:
the method comprises the following steps of building main structure construction, window construction, water spraying test, external vertical surface heat preservation and decoration construction, which are transferred to three construction areas from top to bottom of a building, namely a main structure construction area, a climbing frame auxiliary construction area and a hanging basket auxiliary construction area.

And all installation steps of the window are continuously carried out, so that the adverse effects of water stored in the auxiliary window frame on the construction quality are avoided due to the fact that the installation interval between the auxiliary window frame and the main window frame is too long.
Aiming at the problem that the water flow of a water spraying test can influence the heat preservation and decoration of the outer vertical surface finished in a hanging basket construction area below. And a waterproof measure is arranged at the bottom of the climbing frame, and the water flow falling in the upper water spraying test process is guided to be away from the outer vertical surface of the building.

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the present invention, the use of directional terms such as "upper, lower, left, right" generally means upper, lower, left, right as described with reference to FIG. 3, unless otherwise specified; "inner and outer" refer to the inner and outer relative to the profile of the components themselves. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Concept interpretation:
as shown in fig. 2, the main structure construction area 1 is a position where the construction of a reinforcing bar binding formwork, concrete pouring, and the like of the main structure of the building is performed on the uppermost side of the building.
Wherein climb the supplementary construction district 2 of frame and refer to and receive the parcel protection of climbing frame 4 on the building, climb the region that frame 4 can help bearing material and constructor. Because the top of the building is an open space during construction of the building, the open space is internally used for construction operation of the building main body. The area where the main construction of the building is being performed on the uppermost floor of the building is called a main structure construction area 1. The scaffold assisted construction zone 2 does not include the uppermost open space and the area where the construction of the main building body is being performed, although this area is also protected and affected by the scaffold 4.
The hanging basket auxiliary construction area 3 refers to an area where people and building materials are conveyed in a hanging basket mode to carry out outer elevation construction after the climbing frame 4 moves upwards to the position.
Major structure construction district 1, climb the supplementary construction district 2 of frame and the supplementary construction district 3 of hanging flower basket are three dynamic region, and along with going on constantly of construction, building subject's height constantly increases, building subject's construction position and climbing frame 4 are also constantly becoming high carrying on, therefore major structure construction district 1 here, climb the supplementary construction district 2 of frame and the supplementary construction district 3 of hanging flower basket and be the position of three construction district and also can dynamic change thereupon, can be along with building subject's construction progress and climb the rising of frame 4 and constantly improve. A certain floor of the building in the early stage is a main structure construction area 1, the subsequent construction is performed and the lifting of the climbing frame 4 becomes a climbing frame auxiliary construction area 2, and the climbing frame 4 is further lifted to be separated from the floor in the future, and becomes a hanging basket auxiliary construction area 3. The position is subjected to main structure construction, window installation and water spraying test, and finally heat preservation construction and outer facade decoration construction are carried out, and three complete construction stages are achieved.
The method aims to solve the problems that in the traditional residential building construction, the construction of a building main body, the construction and water spraying test of a window and the heat preservation and decoration construction of an outer vertical face need to be finished and then another construction is carried out, so that the construction period is prolonged and the construction cost is increased on the whole. The invention firstly provides a construction method of a cast-in-place building outer wall based on a climbing frame, as shown in figures 1 and 2.
A construction method of a cast-in-place building outer wall based on a climbing frame is characterized in that a building main body is sequentially divided into a main structure construction area 1, a climbing frame auxiliary construction area 2 and a hanging basket auxiliary construction area 3 from the top to the bottom,
the construction method comprises the following three construction steps which can be carried out simultaneously or in any sequence:
s21, carrying out construction operation on the main structure of the building in the main structure construction area 1 at the top of the building;
s22, sequentially carrying out template dismantling, acceptance inspection, window installation and water spraying tests in the climbing frame auxiliary construction area 2;
arranging a waterproof measure at the bottom of the climbing frame auxiliary construction area 2 to guide the water flow falling in the upper water spraying test process to be far away from the outer vertical surface of the building;
s23, arranging a construction hanging basket in the hanging basket auxiliary construction area 3; and the upper half part of the hanging basket auxiliary construction area 3 is subjected to heat preservation construction, and the lower half part is subjected to outer facade decoration construction.
The construction of the main structure at the top of the building is not different from the prior art, and the construction operation of the main structure such as reinforcement, formwork erection and concrete pouring is carried out, which is not repeated herein.
The climbing frame auxiliary construction area 2 and the hanging basket auxiliary construction area 3 are isolated through a waterproof measure at the bottom of the climbing frame 4, and when the climbing frame auxiliary construction area 2 is used for a water spraying test, sewage flows to the hanging basket auxiliary construction area 3 below along the outer vertical surface. Therefore, when the climbing frame auxiliary construction area 2 is used for carrying out window installation and a water spraying test on a window, the hanging basket auxiliary construction area 3 below is erected with the hanging basket for carrying out heat preservation construction and decoration construction of the outer vertical surface.
Climb the outer facade outside of the supplementary construction area 2 region of frame and have and climb frame 4, climb frame 4 and can provide the space that stable personnel stood the construction to and bear the used material of construction, consequently climb the construction speed that the outer facade part of the supplementary construction area 2 of frame that accelerates that frame 4 can be great in the utilization, reduce the construction degree of difficulty and improve construction safety nature. Before the water spraying test is needed, a waterproof measure is arranged below the water spraying test.
And the decoration construction of the facade must be carried out after the heat preservation construction is finished. Therefore, in order to accelerate the construction progress, the hanging basket auxiliary construction area 3 is divided into an upper part and a lower part, the upper part is firstly subjected to heat preservation construction on the exposed concrete outer vertical surface, and then the lower part is subjected to decoration construction of the outer vertical surface at the position where the heat preservation construction is finished.
Any floor of the climbing frame auxiliary construction area 2 is subjected to template removal, acceptance, window installation and water spraying tests in sequence from first to last according to time, and the sequence of the four construction projects on the same floor or the same position cannot be changed. Therefore, the template removal, acceptance, window installation and water spraying test are sequentially carried out from first to last in the time sequence or are sequentially carried out from top to bottom in the space sequence in the climbing frame auxiliary construction area 2. Or a mixture of temporal and spatial order. Specifically, the work with high construction speed and short construction time is arranged in the same floor according to the time sequence, the working procedure with long construction time is arranged in a plurality of floors to be continuously carried out, and finally the arranged floors are arranged from top to bottom according to the sequence of four items of template removal, acceptance, window installation and water spraying test. As shown in fig. 1, the formwork removal work is performed by separately setting up N-1 floors, and then the preliminary work of acceptance and window installation is arranged at N-2 floors, and then the installation of windows is performed in three consecutive floors from N-2 floors to N-4 floors. And finally, the final work of the short-time water spraying test and the window installation is installed on the N-4 layers.
In a word, any floor in the climbing frame auxiliary construction area 2 only needs to be guaranteed to sequentially pass through four procedures of template removal, acceptance inspection, window installation and water spraying test from first to last according to the time sequence.
Because materials such as formwork support columns and the like used in the main structure construction need to be circulated as soon as possible, the formwork dismantling is carried out on the floors at the top of the climbing frame auxiliary construction area 2 close to the main structure construction area 1. And meanwhile, after the template is dismantled, wall defect repair and screw hole plugging operation are required.
As shown in fig. 1, the window installation includes the steps of:
a) mounting a window auxiliary frame;
b) painting waterproof window plug seams;
c) installing a main window frame and glass;
the steps a), b) and c) are sequentially carried out on different floors from top to bottom.
Because the climbing frame 4 brings great convenience to the construction of the outer wall, the climbing frame auxiliary construction area 2 also carries out the installation of an air conditioner plate, the installation of a drainage vertical pipe and the installation of balcony rails on the outer vertical surface after acceptance; the air conditioning plate can not be the air conditioning plate which is arranged in a cantilever manner due to the form that the air conditioning plate is retracted into the groove of the outer vertical surface when needed, so that the air conditioning plate is prevented from influencing the lifting of the climbing frame 4.
In the prior art, the heat insulation operation of an outer wall is generally carried out firstly, and then a guardrail is installed. When the heat preservation operation is carried out, the guardrail installation position needs to be avoided, and then the leveling repair needs to be carried out again after the installation of the guardrail is completed. Therefore, the installation of the balcony guardrail is completed when the heat insulation construction is carried out on the balcony part, and the leveling is completed by smearing the heat insulation mortar once.
The waterproof measure is set and finished before the water spraying test, as shown in fig. 3, the left side of fig. 3 is a building outer wall, the right side of fig. 3 is a climbing frame 4, and a water diversion plate 5 is arranged at the bottom of the climbing frame 4. The waterproof measure includes that the upper edge is lapped on the diversion plate 5 on the wall body below the water spraying test, the lower edge of the diversion plate 5 extends towards the direction far away from the outer vertical surface, and the diversion plate 5 is connected with the climbing frame 4 and moves along with the climbing frame 4. Because the diversion plate 5 moves upwards synchronously with the climbing frame 4, the diversion plate 5 can be positioned at the bottom of the climbing frame 4 all the time.
When the waterproof measure is used, the method comprises the following four steps:
firstly, moving a water diversion plate 5 to be abutted against a wall body before a water spraying test;
then, carrying out a water spraying test, wherein the water guide plate 5 guides the water flow falling from the water spraying test to protect the outer vertical surface of the building;
then after the water spraying test is finished and before the climbing frame 4 is lifted, the water guide plate is movably separated from the outer wall of the building, and then the climbing frame 4 is lifted;
and finally, after the climbing frame 4 is lifted and is finished and before a water spraying test experiment, the water guide plate 5 is newly led to move to be abutted against the wall body.
The diversion plate is installed on climbing frame 4, and together the preparation is accomplished when making climbing frame, and once preparation can use the construction completion, and when moving climbing frame 4 at every turn, only need let the diversion plate break away from the facade of wall body, avoid diversion plate 5 to influence the motion of climbing frame 4. Let the diversion board move about at ordinary times and contact with the wall body, performance diversion board's diversion function. The length of the diversion plate 5 is determined according to the concrete building type and the position of the constructed building for carrying out the water spraying test. For example, most of the gable walls on two sides of the building do not have windows, so that the water diversion plates 5 do not need to be installed at the positions of the gable walls on the two sides because of no need of arranging waterproof measures.
Meanwhile, in order to match with the waterproof measure at the bottom of the climbing frame 4, the invention also designs a waterproof protection structure for the outer vertical surface of the water spraying test, as shown in fig. 3 and 4.
